I just bought a family one, two adults in house and kids. Me, my daughter and her 3 kids. It cost 119 for family and you can do a add on guest for 50 so 119 + 50.
Grand parent plus guest
Just call the zoo office and they can help you with getting something that meets your needs.
Its possible. Just go to the services offices just to the right of the main gate and you'll have all your questions answered as they walk you through the membership process.
Family pass
Yes I believe it's about 1:40
A membership is 120 im not sure about the guest but if you call the office they will help you and let you know.
